A built-in guard prevents accidental changes and other tampering and protects these thermostats from damage. These thermostats regulate the temperature in HVAC systems that use direct electrical power. They’re often used with baseboard and wall heaters.
DPST (double pole, single throw) thermostats control two circuits, so they have an “off” setting that cuts power to the thermostat. As a result, they’re more energy efficient and slightly safer than SPST (single pole, single throw) thermostats, which stay at a low setting instead of turning off completely.

Set these thermostats to adjust the temperature at certain times each day. They control low-voltage HVAC systems. You can lock the settings to prevent unwanted or accidental changes, which is helpful in public areas. If the power fails, these thermostats have battery backup to retain your program.
Touchpad thermostats can be used with a remote sensor (sold separately) that takes temperatures up to 300 ft. from the thermostat.
Single-stage thermostats work with systems that have only one speed. Multistage thermostats work with systems that have up to three heating speeds and two cooling speeds.
Thermostats with a daily program function can have an individual program for each day of the week.

Control, monitor, and program your HVAC system from anywhere. These thermostats connect to a Wi-Fi network, so you can use a computer, tablet, or smartphone to view and adjust settings. You can also lock the settings to prevent accidental changes or tampering in public areas. They control low-voltage, multistage HVAC systems that have up to three heating and cooling speeds. Use them to set an individual program for each day of the week.
Location-sensing thermostats connect to an app that tracks the location of your mobile device. They can automatically adjust the temperature based on your distance from the thermostat. Use the app to send push notifications for service reminders, unexpected temperature changes, and interruptions to the Wi-Fi connection.
Thermostats with a humidity/temperature sensor also detect motion. Place the remote sensor in a room or enclosure to maintain a consistent climate. To help save energy, they can raise or lower the temperature when no motion is detected.

Snap-Action Thermostats
![](/prerenderstable/mvPRE/contents/gfx/imagecache/862/8624n11-@halfx_637581596625950799.png?ver=imagenotfound)
Also known as snap discs, these thermostats switch on cooling systems or switch off heating systems when equipment gets too hot. Each thermostat has five temperature options for switch activation; choose the one that best suits your application.
Unlike heat-actuated switches, these thermostats reset automatically, saving you the effort of replacing a melted fusible link. To calculate their reset temperature, subtract their differential temperature from the temperature you set them at. For example, a thermostat set at 100° F with a 20° F differential will reset at 80° F.
Normally open thermostats are also known as low-limit thermostats—they turn on at a set temperature. They’re good for use with fans and blowers.
Normally closed thermostats are also known as high-limit thermostats—they turn off at a set temperature. They’re often used with electric water heaters, stoves, and furnaces.

Reverse-Action Air-Powered Thermostats

Also known as a two-pipe thermostat, this thermostat uses compressed air for power. Use when electricity is not practical or available for controlling your HVAC system. It is reverse action, so as the temperature goes up, the pressure in the system goes down.
Air consumption is measured in standard cubic inches/minute (scim).
The included universal fitting kit consists of a cover, mounting plate, dial stops, screws, tubing reducers, tubing, and mounting hardware. Internal filters are for the air connections and are included.

Proportional HVAC Damper Actuators

This actuator provides better control than incremental actuators because it is constantly being positioned in response to duct airflow requirements. Use to automatically adjust dampers to regulate airflow. It attaches to the damper shaft to rotate it open and closed when signaled by a controller (not included). Actuator can be set to return the damper to an open or closed position if the power fails. Use the crank for precise adjustments.

When duct airflow varies from the setpoint, these actuators open and close until the system requirement is restored. Use to automatically adjust dampers to regulate airflow. Actuators attach to the damper shaft to rotate it open and closed when signaled by a controller (not included).
